Field of the Invention
The present invention relates to a film coated tablet comprising a solid dispersion of selexipag or crystalline polymorph thereof, wherein the solid dispersion further comprising at least one binder and solvent. Furthermore, the tablet is obtained using an effective process.
Background of the Invention
Selexipag is prostacyclin receptor agonist that causes vasodilation in pulmonary vasculature and is used in the therapy of pulmonary arterial hypertension (PAH). Selexipag also known as 2-(4-((5,6- diphenylpyrazin-2-yl)(isopropyl)amino)butoxy)-N-(methylsulfonyl)acetamide can be represented by the following chemical structure according to Formula I:
Figure imgf000002_0001
Formula I: Selexipag
Depending on the dose strength, each round film-coated tablet for oral administration contains 200, 400, 600, 800, 1000, 1200, 1400, or 1600 mcg of Selexipag. The Uptravi® film-coated tablet is a standard immediate-release tablet that contains D-mannitol, corn starch, low substituted hydroxypropylcellulose, hydroxypropylcellulose, and magnesium stearate. The tablets are film coated with a coating material containing hypromellose, propylene glycol, titanium dioxide, carnauba wax along with mixtures of iron oxide red, iron oxide yellow or iron oxide black.
Selexipag is considered to be a BCS (Biopharmaceutics Classification System) Class II drug, i.e. having high permeability and low solubility.
EP3481807 (Al) discloses novel crystalline forms of selexipag and its process for the preparation thereof. WO 2017/029594 describes the preparation of amorphous selexipag by dissolving the drug in a suitable solvent, e.g. acetone, and removing the solvent by, e.g., evaporation, spray-drying or freeze- drying.
In prior art, there are also several patents which disclose selexipag in oral pharmaceutical dosage forms. However, despite the dissolution problem of selexipag, an effective formulation and method has not been disclosed.
There still remains a need in the art to provide an improved a film coated tablet comprising selexipag or crystalline polymorph thereof having high solubility, excellent physicochemical properties and accordingly a high bioavailability and a long-term stability.
Detailed Description of the Invention
The main object of the present invention is to provide a film coated tablet comprises a solid dispersion of selexipag or crystalline polymorph thereof with having the desired level of dissolution rate and high stability and excellent physicochemical properties, such as flowability, compressibility, homogeneity, and content uniformity which overcomes the above-described problems in the prior art and have additive advantages over them.
Another object of the present invention is to provide a process for preparing a film coated tablet composition comprising selexipag or crystalline polymorph thereof. The process is a simple, rapid, cost effective, time-saving, and industrially convenient method.
Like the other poorly soluble in water molecules, low solubility of selexipag results in low dissolution. Also, selexipag or crystalline polymorph thereof is used small proportion that can lead to considerable problems during the manufacture of the composition with regard to the uniformity of the content of active agent in the individual composition units. Because of problems uniformity of the content, the active substance may interact with several excipients. It reflects that content uniformity play important role in the dissolution of the drug.
Selexipag or crystalline polymorph thereof presents in low amount in the tablet. Thanks to a solid dispersion at the present invention, the film coated tablet which has a low amount of selexipag or crystalline polymorph thereof has been developed with excellent physicochemical properties. Also, this provides the desired stability and dissolution profile of the tablet.
